• One does not feel any hurt or pain when he commits evil deeds and sins
• One finds both pleasure in committing sins and tranquility after doing them
• One looks after less important matters and neglects more important and critical ones
• One dislikes the truth and has difficulty accepting or submitting to it
• One feels discomfort being in the company of the righteous and feels comfort in the company of the sinful
• One is susceptible to misconceptions and doubts, and is attracted to debates and arguments about them rather than to reading Qur’an and other such beneficial acts
• One if not affected by any kind of admonition
